This is the text (if you need help).
One in five of the world's plants is in danger. Botanic gardens could save plants. They could help to protect them. These gardens contain about 100,000 kinds of plants, including rare ones. Scientists looked at many plants in botanic gardens. They said they know what plants are missing from botanic gardens.
Botanic gardens may be the best hope for saving endangered plants. If we do not protect plants, we could have problems with food in the future. We will also have problems with climate change. Plants are in danger because of people. We cut down forests for farms and cities.
